| Operation Type | Typical Herd Size | Housing System | Typical Market |
|---|---|---|---|
| Small‑scale / Family farm | < 50 cows | Pasture‑based or tie‑stall | Local direct‑sale, farmers’ markets |
| Medium‑scale commercial | 50–250 cows | Free‑stall or compost‑bed barns | Regional processors |
| Large‑scale industrial | > 250 cows | Confined‑space, automated milking parlors | National/international processors |
Choice of system depends on land availability, capital, labor, and market goals.
| Nutrient | Function | Main Sources |
|---|---|---|
| Energy (carbohydrates, fats) | Milk synthesis | Corn, barley, soybean meal, fats |
| Protein (rumen‑degradable & undegradable) | Tissue repair, milk protein | Soybean meal, canola meal, alfalfa |
| Fiber (NDF) | Rumen health, chewing activity | Forage, silage, hay |
| Minerals & Vitamins | Metabolic processes | Salt blocks, mineral mixes, fortified premixes |
| Step | Key Practices |

| Pre‑milking | Clean udder, apply pre‑milking disinfectant, check for abnormalities. |
| Milking | Use proper suction pressure (≈ 40 kPa), maintain milking time 5–7 min per cow. |
